Objectives

Narrative objectives1

Chronic pain after breast cancer surgery has harmful effects on patients' daily life. Paravertebral block can prevent not only acute but chronic pain after breast cancer surgery, although the block is not easily put into practice because of technical difficulty or necessity to change patients' position. Recently, thoracic wall blocks have been reported by Blanco and in hope that it gives similar analgesic efficacy as paravertebral block with less risks, however there are no reports comparing analgesic efficacy of paravertebral block with thoracic wall blocks. Although there are several scales evaluating postoperative pain including VAS or NRS, Quality of Recovery (QoR) have been set up to assess the impact of postoperative morbidity on patients' ability to return to normal function and quality of life. Among those assessment scales, QoR-40 has been mainly applied. It consists of 40 questions including five dimensions: psychologic support, physical comfort, emotional state, physical independence, and pain, and there is a report suggesting that paravertebral block improve QoR-40 after ambulatory breast tumor resection. In this randomized, noninferiority trial, we hypothesized that thoracic wall blocks provides preserving effect of QoR-40 at least as good as paravertebral block after breast cancer surgery.
